2.1 Top 5 Active Issues:
We consider active issues to be issues that that have been commented on most frequently within the last week. Bot comments are omitted.
-
The RealParent on Microsoft.Maui.Controls.Shapes.RoundRectangle has been Garbage Collected: This issue reports a recurring error where the RealParent on Microsoft.Maui.Controls.Shapes.RoundRectangle is being garbage collected unexpectedly, which started occurring after the latest release. The user is unsure how to reproduce the problem, notes it is a regression from previous behavior, and has not found any workaround, seeking guidance on verifying the exact MAUI version and resolving the issue.
- The comments focus on clarifying the exact MAUI version in use, with suggestions to specify a fixed MAUI version in the project file and to try recompiling with different versions to identify when the bug appears. It is also noted that a related issue was fixed in a prior service release, and the user is guided on how to confirm and update to the latest MAUI version to test if the problem persists.
- Number of comments this week: 6
-
Update "Release Versions" wiki page: This issue requests an update to the "Release Versions" wiki page, which has not been maintained since Service Release 8 despite newer releases being available. The requester highlights the page's usefulness in avoiding compilation errors by knowing the correct tooling versions needed when upgrading .NET MAUI apps and asks if the documentation can be kept current or found elsewhere.
- The comments discuss the actual dependency of .NET MAUI service releases on various SDKs, noting that while the releases primarily rely on a NuGet package compatible with .NET 9 SDK, there are occasional dependencies on specific tooling versions like XCode. Commenters emphasize the practical value of the wiki page for troubleshooting version conflicts, managing multiple app frameworks, and deciding when to upgrade or pin versions to avoid bugs.
- Number of comments this week: 4
-
[Android] Picker - System.InvalidOperationException: VirtualView cannot be null here (SIGABRT) with sample: This issue describes a crash occurring on Android when a Picker popup remains visible during page navigation, causing a System.InvalidOperationException with the message "VirtualView cannot be null here" and ultimately leading to an application crash. The problem is reproducible on MAUI versions 9.0.0, 9.0.90, and 9.0.110, and it appears to be a regression introduced after version 9.0.90.
- The comments confirm the issue is reproducible on specific MAUI versions and Android, noting it does not occur on versions below 9.0.90. Additionally, a regression pull request has been identified as the likely cause of the problem.
- Number of comments this week: 2
-
Incorrect number in alt text "dot net bot in a hovercraft number nine" instead of "number ten":A11y_.NET Maui Template_Talkback: This issue reports that the alt text for an image in the .NET Maui template app incorrectly states "dot net bot in a hovercraft number nine" instead of the correct "number ten," which can mislead users relying on screen readers. The problem was observed on an Android device using Talkback, and the incorrect alt text could cause confusion or misinterpretation for visually impaired users.
- The commenters noted that the fix for this alt text was already implemented in a related pull request for the .NET 10 project and questioned the source of the reported sample, as the Developer Balance app does not use the dotnet bot image. The issue reporter provided a testing APK for verification and requested the latest APK to confirm the fix and close the issue.
- Number of comments this week: 2
-
[Android] Unexpected Line Breaks in Android, Label with WordWrap Mode Due to Trailing Space.: This issue addresses unexpected line breaks occurring in Android when using a label with LineBreakMode set to "WordWrap," where trailing spaces cause words to shift to a new line, resulting in inconsistent UI appearance. The reporter is uncertain if this behavior is intentional or a platform limitation and requests clearer documentation or a fix if it is a bug.
- The comments clarify that this behavior is intended in MAUI due to how native Android and iOS text views handle word wrapping, refusing to break words mid-word unless a different mode is used. Additionally, a discrepancy is noted between Windows and Android platforms, where Windows aligns the wrapped text correctly without leaving trailing space, but Android does not, as demonstrated with comparative images.
- Number of comments this week: 2
2.2 Top 5 Stale Issues:
We consider stale issues to be issues that has had no activity within the last 30 days. The team should work together to get these issues resolved and closed as soon as possible.
- Nullable Enums do not bind in XAML: This issue describes a problem where nullable enums do not properly bind in XAML for a bindable property within a custom control, with the setter method not being triggered during binding. The user reports that this occurs across iOS and Android platforms in version 8.0.80 SR8, and the suggested workaround is to avoid using nullable enums by adding an explicit unset or none value to the enum instead.
- App crash after invoked FilePicker.Default.PickAsync in administrator mode and release mode of the Unpackaged app: This issue describes an application crash that occurs specifically when invoking the FilePicker.Default.PickAsync method in an unpackaged app running in administrator mode and release configuration. The problem is reproducible by publishing the app with certain .NET 8.0 Windows settings, launching it as an administrator, and attempting to choose a file, which unexpectedly causes the app to crash instead of functioning normally.
- Global defined EventTriggers get triggered twice: This issue describes a problem where EventTriggers defined globally in a style cause the associated invoke method to be called twice, resulting in duplicate event handling. The user notes that applying the EventTrigger through a named style with a key triggers the invoke method only once, indicating a discrepancy in behavior between global and keyed style definitions across multiple platforms including iOS, Android, and Windows.
- Path with ArcSegments is sporadically drawn offset from expected arc: This issue describes a sporadic rendering problem in .NET Maui where arcs drawn using ArcSegment within a PathFigure or PathGeometry appear slightly offset from their expected starting positions, particularly for large arcs greater than 180 degrees. The offset causes clipping against bounds and is more noticeable with thicker strokes and near the 180-degree threshold, affecting Windows, Android, and iOS platforms, with partial workarounds involving manual line segments reducing but not fully eliminating the problem during animations.
- .NET Maui does not support FontAutoScalingEnabled for windows platform: This issue addresses the lack of support for the FontAutoScalingEnabled property in .NET Maui when running on the Windows platform, causing text labels to scale incorrectly with changes in display scaling settings. Specifically, when FontAutoScalingEnabled is set to false, the text size still increases with higher Windows display scaling factors, which should not occur according to the expected behavior.
2.3 Open Issues
This section lists, groups, and then summarizes issues that were created within the last week in the repository.
Issues Opened This Week: 17
Summarized Issues:
- Android UI and Navigation Issues: Several Android-specific UI problems affect navigation and visual consistency, including persistent ToolbarItem icons from previous pages causing visual glitches, Picker popups remaining visible after navigation leading to crashes, and ControlTemplates not sizing properly without explicit height settings. These issues cause inconsistent user experiences and application crashes that lack current workarounds.
- [issues/31727, issues/31731, issues/31797]
- Crash and Exception Regressions: Multiple crashes and exceptions have been reported across platforms, such as a System.NullReferenceException in CarouselView on Windows when ItemSource is null, a Java.Lang.RuntimeException on Android due to large bitmap rendering, and garbage collection of RealParent in RoundRectangle on Android causing errors after the latest release. These regressions represent new failures compared to previous versions and impact app stability.
- [issues/31740, issues/31760, issues/31780]
- Compilation and Build Failures: Users face build and compilation issues including a XAML internal error after installing the latest Android SDKs causing project template failures, and inability to target or build .NET MAUI projects for the Tizen framework due to unrecognized platform identifiers and missing versions.

These issues affect usability and accessibility compliance.
- [issues/31739, issues/31750]
- Data Binding and Gesture Handling Problems: Issues with data binding include thousands of XC0022 warnings due to missing x:DataType in XAML bindings and loss of bindable properties like commands in CollectionViewHandler2 on iOS when item order changes, causing gestures to stop firing. These problems degrade performance and break expected interactive behaviors.
- [issues/31734, issues/31764]
- Platform-Specific UI Behavior Differences: Differences in UI behavior across platforms are noted, such as Android labels with LineBreakMode="WordWrap" leaving trailing spaces that differ from Windows, and the WinUI TabbedPage allowing multiple tabs to be selected simultaneously on Windows, continuing a previously unresolved issue. These inconsistencies affect cross-platform UI reliability.
- [issues/31782, issues/31799]
- Documentation and Versioning Updates: There is a need to update the "Release Versions" wiki page to include the latest service releases (SR9, SR10, SR11) to provide accurate tooling version information and help developers avoid compatibility and compilation issues when upgrading .NET MAUI apps. Keeping documentation current is essential for smooth development workflows.
- [issues/31711]
- Code Cleanup Requests: A request has been made to remove the outdated OnDestroy override from ShellFragmentContainer due to its potential to cause exceptions related to dispatcher retrieval, reflecting a need to clean up legacy code that may introduce instability.
- [issues/31716]
- Blazor Hybrid Regression: The Blazor Hybrid Web template that works on WebAssembly with .NET 9 fails after upgrading to .NET 10 RC1, despite MAUI Blazor functioning correctly, indicating a regression affecting Windows Web/WASM platforms.
